mixed with the ashes.

PROCESS OF UTILIZING COKE-BREEZE.

No Drawing.

To all whom it may concern:

Be it known that I, HENRY A. Toast.-

MAN a citizen of the United States, residing at Warren, in the Territory of Arizona, have invented new and useful Improvements 'in Processes of Utilizing Coke-Breeze, of

which the followin is a specification.

My invention re ates to improvements in artificial fuel, and com rises a method of preparing artificial fue from coke breeze and slack or washed coal.

The principal object of my invention is to utilize the coke breeze coming from coke ovens, and which is at present almost a waste roduct and in most cases is an expense or its removal. I propose-to convert this waste product into a source of revenue by a. simple and comparatively .inex ensive process, converting it into marketab e coke.

As is well known, from two to five per cent. of the coal which is charged into the ovens is lost in the coke breeze which is The coke breeze will analyze between 25 and 35 per cent. of ash, and it is the common practice to haul or ship this away, to be used merely for filling purposes or to a dump.

I have found that the coke of the coke breeze will amalgamate or fuse with coal under proper conditions, providing the ash is first removed. The latter is, however, an.

important aiud essential step in my process. My method of transforming the coke breeze into a marketable fuel consists in first pulverizing the breeze, by passing it be-v tween rolls or other suitable crushing apparatus until the lumps are reduced to about the size of slack coal. After the breeze has the coke breeze, clean surfaces of coke are thereby left exposed, which are brought into Specification of Letters Patent.

direct and intimate contact with the clean coal in the mixture, 30 that the particles of coke and coal may be thoroughly amalgamated during the succeeding coking step of the process. This mixture is charged into the coke ovens and heated in the manner of coking coal. During the process of cokin the particles of coke are"practically una fected while the particles of coal will fuse to the coke particles and then coke, thus forming a resulting mass of coke of marketable quality.

I have found that the proportions of coke breeze and washed coal or slack that ma be mixed may vary quite largely, de en ing izing coke breeze and the manner in which.

the same may be carried out, I claim- '1. The method of utilizin coke breeze, which com rises pulverizing t e coke breeze, cleaning. t e as therefrom mixing the cleaned coke breeze with, suitable proportions of clean cokingslack,. and subjectin the mixture to heat sufiicient to fuse and coke the mass.

2. The method of utilizin coke breeze, which com rises ulverizing t e coke breeze, cleaning t e as therefrom, mixing the cleaned coke particles with suitable proportions of clean coking slack, and subjecting the mixture to a tem erature sufliclent to cause the articles of t e mixture to cohere and coke t e slack.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit-' nesses. I p
